1. Types of Energy Chapter 9

2. What is Energy? Energy is the ability to do work.

3. What is Energy? When one object does work on another, energy is transferred from the first object to the second object.

4. What is Energy? The metric unit for energy is the joule (J).

5. Mechanical Deals with motion Include kinetic and potential Ex.  fan, sound, moving air

6. Mechanical

7. Electromagnetic Caused by moving electrons (negative particles) Includes the EM spectrum Ex.  electricity, magnets, light, x-ray, etc.

8. Electromagnetic

9. Thermal Means “Heat” Caused by moving particles (kinetic energy)

10. Thermal

11. Chemical Holds atoms together to form chemical bonds Ex  food, batteries, fuel

12. Chemical

13. Nuclear Found within the nucleus of an atom Extremely strong Used to create nuclear power or nuclear weapons.

14. Nuclear

15. Law of Conservation of Energy States “Energy can not be created nor destroyed.” Energy simply changes types (forms)

16. Law of Conservation of Energy In a system the energy in must equal the energy out Energy In = Energy Out

17. Law of Conservation of Energy Energy In=Energy Out EM Thermal (heat) Mechanical (moving air & sound)

18. Law of Conservation of Energy Energy In=Energy Out Chemical (wood) Thermal (heat) EM (light) Mechanical (sound)

19. Law of Conservation of Energy Energy In=Energy Out EM (electricity) EM (Light) Thermal (heat)

20. Law of Conservation of Energy Energy In=Energy Out Chemical EM (electricity)

21. Law of Conservation of Energy Energy In=Energy Out Chemical (gasoline & battery) Mechanical (motion) Thermal (heat from friction)

22. Law of Conservation of Energy Energy In=Energy Out Chemical (food) Mechanical (movement) Thermal

23. Law of Conservation of Energy Energy In=Energy Out Chemical (battery) Mechanical (sound) EM (light)
